Irish Transport and General Workers' Union

The Irish Transport and General Workers' Union (ITGWU) was a major Irish trade union that existed from January 1909 to 1990, when it merged into SIPTU. The ITGWU was founded by Irish socialist James Larkin and several dock workers, and it grew into a general union, taking part in the syndicalist Dublin lockout of 1913 and several other strikes. After Larkin moved to the United States in 1914, William X. O'Brien became the new leader of the ITGWU, and he became enemies with Larkin when Larkin founded the Workers' Union of Ireland. In 1990, the two unions merged to form SIPTU after years of reconciliation efforts.
